In the Second World War, hundreds of thousands of children were evacuated from British cities and sent to areas of the country where it was regarded that they would be safer from bombing. They went to stay with complete strangers, many of whom were unenthusiastic about having a young guest staying with them for a long period of time. This is the second story about young evacuees. It tells how their lives have changed and how they get involved in a dangerous mystery in their new home in the country on the Isle of Wight. Their adventure leads them to TREACHERY!
